From the Photonics Spectra article linked below: "Due in large part to Imes’ early experiments, the shift in scientific circles to a quantum worldview brought about new applications and interpretations of experimental data. In fact, the thesis of Imes’ first paper predicted this eventual shift." #QuantumPhysics #ElmerImes #QuantumWorldView #Discovery #History #Innovation

🚀 Excited to have completed an insightful summer school course on Quantum Mechanics for Photonics! 🌟 A huge thanks to Dr. Maksim Shundalau from the University of Salerno, Italy, for leading this course. Hosted by the University of Eastern Finland, the course provided an in-depth exploration of the quantum mechanics underlying molecular systems and low-dimensional materials. The course also included hands-on modeling of the structure and different properties of diatomic and polyatomic molecules, using Quantum ESPRESSO and GAMESS software. #QuantumMechanics #Photonics #MolecularSystems #LowDimensionalMaterials #QuantumESPRESSO #GAMESS #DFT #MolecularModeling #UniversityOfEasternFinland #LifelongLearning

Paper day is always a happy day! Especially if it comes in pairs :) The first is an extensive review of Attosecond Transient Absorption and Reflection spectroscopy of solid-state samples to study ultrafast electron dynamics. After a detailed presentation of the state of the art, we go deep into the fundamentals of both techniques, analyzing clear advantages and disadvantages, and finally concluding with challenges and future directions. https://lnkd.in/dFD8848w In the second work, we show how to use a simultaneous attosecond streaking measurement to calibrate the absolute delay of transient spectroscopy data with attosecond precision. https://lnkd.in/dy4UcZkB Check them out!

Congratulations to my co-authors Maximilian Weissflog, Romain Dezert, Sina Sinaravi and Adrien Borne for the publication of our article Nonlinear nanoresonators for Bell state generation (https://lnkd.in/eZt9a2Dr)! In this work, featured in Applied Physics Reviews special issue on Quantum Metamaterials, we explore the possibilities offered by nonlinear nanoresonators as miniaturized sources of biphoton states with highly complex and tunable properties. Thanks to a new modeling approach, we unveil, amongst others, a regime where the generated multimode biphoton state is maximally entangled in the polarization degree of freedom, and naturally frequency entangled in a very broad spectral range. This contributes to the understanding of the physics of photon-pair generation in nanoscale systems, and stresses out that those systems are natural canditates for the future quantum technologies.

Two papers out on the same day! If you want to know more about attosecond transient absorption and reflection spectroscopy in solids and how we can use it to study early dynamics induced by light fields, take a look at our review in APL Photonics: https://lnkd.in/d_hVtuXe In Journal of Physics: Photonics, instead, we discuss how we calibrate the absolute delay of transient reflectivity experiments with attosecond precision by analytical fitting of streaking measurements: https://lnkd.in/dGCW-xs7 Check them out!

I'm delighted to announce that I'll be presenting at the 16th Pisa Meeting on Advanced Detectors in the Low Temperature, Quantum, and Emerging Technologies Session. I will share with the detector communities my vision on the use of quantum-limited amplifiers for the next generation of fundamental physics experiments. #PisaMeeting2024 #AdvancedDetectors #QuantumTechnologies #LowTemperatureDetector #LTD #EmergingTechnologies #QuantumAmplifiers #FundamentalPhysics

The search and discovery of novel topological properties of matter have emerged as one of the most sought-after treasures in modern physics, both from a fundamental physics point of view and for finding potential applications in next-generation quantum science and engineering.

💥 The paper “The Effect of Ultrastrong Magnetic Fields on Laser-Produced Gamma-Ray Flashes” by P. Hadjisolomou, R. Shaisultanov, T. M. Jeong, P. Valenta, and S. V. Bulanov from ELI Beamlines has been published in Physical Review Research. ➡️ Laser produced gamma-photons can make an important impact on such applied and fundamental physics as studying photo-nuclear reactions, generation of electron-positron plasmas and testing nonlinear quantum vacuum texture. ➡️ These applications require high gamma-photon yield and strong collimation. Here we study gamma-flash generation in the interaction of strong laser light with solid density target. We propose the addition of a constant magnetic field to the laser-solid interaction to obtain the aforementioned desired gamma-photon properties. The gamma-ray flash spatial and spectral characteristics are obtained via quantum electrodynamic particle-in-cell simulations. When the constant magnetic field aligns with the laser magnetic field, then the gamma-ray emission is significantly enhanced. Moreover, the gamma-photon spatial distribution becomes collimated, approximately in the form of a disk.

"...The information connected to the phase is that required to obtain the time evolution of the particle as a persistent entity starting from a random succession of bits. It can be considered as the information provided by conservation principles. The meaning of the so-called “#quantum potential” in this context is briefly discussed."
